To be honest, I'm not sure it is good idea. I'll explain why: In C++ JSON object has valuesemantics, unlike the reference semantics in JavaScript, so using NULL pointer or pointer to cppcms::json::null would be alien. That is why object cppcms::json::null exists, it is dummy object that represents null value and it works perfectly fine. Using pointer as substitution may be misleading as users may assume that they assign pointers to json object and not values themselves.

Thanks Artyom, it worked perfectly :) Now following the json example, Im trying to publish the content using: my_object.save(response.out(),cppcms::json::compact); Everything seems ok, but looking at the output type it shows: text/html but, it needs to be: text/javascript How can I do that?

CppCMS asychrnonous application can receive completion notification on data trasfer and thus for example postpone or change stream parameters according to the performance. Also, the same is valid for syncrhonous operations. i.e. if you write to output stream you can get blocked until operation completes and very the transfer parameters. So you can do whatever you feel is right. Using any of the protocols.

In both synchronous and asynchonous manner, you can for example hande several hundreds of simultaniuos connections using asynchronous applications. You can also do it via FastCGI, SCGI or use reverse HTTP Proxy. Of course for static content it would better to use real web server. What I can recommend is to use combination of X-Send-File, X-Send-Range and lighttpd to give lighttpd information about what to send. If you are planning to serve everything via CppCMS HTTP server it is not good idea, but I don't see specific problem in video streaming.

A video streaming server will be bound by high disk I/O because certainly you cannot keep all the data in memory. The second aspect is whether you want users to upload their video. If yes then what formats will you support? If you support multiple formats and stream one then you need to convert them. Now conversion needs lots of CPU and RAM so certainly CppCMS seems an excellent choice in this case.

Hi Artyom, I have written a db pool which creates given no. of persistent connections and also dynamically increases connections. Say I create the pool globally and in the code where dispatcher calls functions which perform actual business logic I acquire one connection. Is it guaranteed that connections will execute in multi-threaded fashion. I have taken care in my db pool that it is thread-safe.

Hi Artyom, Thanks for the prompt response. I was in fact looking for a framework to develop http streaming server for our video portal.

Hello there ! I've need to set a null value on JSON without quotes, I've tried the following: my_object["name"] = NULL; my_object["name"] = "null"; On the first case I've got "my_object": 0 and then "my_object":"null" But I've need "my_object":null Any clue ? Daniel |

Hi all, I have compiled Hello sampe from the Tutorial. Under root it runs perfectly. Under non root user it gets exception in srv.run(): "system: Permission denied". What might I have missed? Thanks, Alexey. |

I'm not familiar with the API of Hypertable but I assume it is not SQL :-) In any case implementing CppCMS backends is not hard as long as you familiar with specific library API.

You can provide a specialization for serialization traits like
namespace cppcms {
serialization_traits<std::vector<page> > {
load(...)
save(...)
}
};
It is generally designed to be used with custom (not-cppcms based) serialization methods.
I woudn't say it is best practice, but it would allow you not to use the "wrapper" class.

It is generally good idea to create two different skins that each one of them contains the code this way you can switch only the skin name and use the same "view" name according to logic/model.

Hi all I have a working cppcms based application and would like to extend it to display the same model's in a completely different way. At the moment I have a touch optimized administration GUI. Is it possible to create an PC browser optimized version (with twitters bootstrap) to display the same models? Should this be the a different skin? thanks -- Christian Gmeiner, MSc |

Hi All!
What is the best practice to serialize vector of struct
(std::vector<struct_name>)?
Now I use ugly method to wrap main struct into struct container with
std:vector member:
struct page_container : public cppcms::serializable {
struct page : public cppcms::serializable {
std::string uuid;
time_t insert_date;
time_t update_date;
void serialize(cppcms::archive &a) {
a & uuid & insert_date & update_date;
}
};
std::vector<page> pages;
void serialize(cppcms::archive &a) {
a & pages;
}
};
page_container pages;
if(!cache().fetch_data("pages", pages)) {
get_pages(pages);
cache().store_data("pages", pages);
}
Thanks in advance!
